Attachment theory originally was focused on early stage development in children by John Bowlby. Later it was expanded as a way to conceptualize relationships beyond the child and caregiver, things like friendships, work colleagues, bandmates, etc.
Examples where modern attachment theory could be used formulate a hypothesis (or analyze if you have more than conjecture):
- why a band breaks up
- why CrunchPad failed (https://techcrunch.com/2009/11/30/crunchpad-end/)
- in interpersonal relations, contradictory, anxious, afraid, erratic behavior - or on the other hand - secure and trusting around someone or a group.
Attachment can explain lasting, functional relationships.
I guess in HN-speak, there could be dyads between startup co-founders, founder <-> employee, investor <-> founder, employee <-> employee. Those cooperational things bubble up into group dynamics and product formation / stuff shipping.
New startup idea: Founder therapy :)
